To provide a device that, from the viewpoint of facilitating slinging work and the like while ensuring the safety of workers around the crane, can appropriately adjust the frequency of alarm to be issued to the workers.SOLUTION: An alarm is not issued when simply a worker P1 carrying a terminal device 40 is present in a designated region R, but the alarm is issued from the terminal device 40 when, as a further requirement, a height h of a hook 17 or suspended load W is equal to or higher than a designated height H. Thereby, the worker P1 can perform slinging work and work associated therewith in the designated region R when the height h of the hook 17 or suspended load W is lower than the designated height H.SELECTED DRAWING: Figure 1
【課題】クレーンの周囲における作業者の安全性を確保しながらもその玉掛け作業等の円滑を図る観点から、当該作業者に対する警報頻度を適当に調節しうる装置を提供する。【解決手段】端末装置40を携帯している作業者P1が単に指定領域Rに存在するだけでは警報が発せられず、フック17または吊荷Wの高さhが指定高さH以上になったことをさらなる要件として当該端末装置40から警報が発せられる。このため、フック17または吊荷Wの高さhが指定高さH未満である状態では、作業者P1は指定領域Rにおいて玉掛け作業およびこれに付随する作業を実行することができる。【選択図】図1
